Specialist authority, not corporate hierarchy.
Organised around the disciplines our clients are accountable for.
Small rooms
Senior people do the work. Nothing is delegated to a team the client has not met.
Plain language
If a position cannot be explained to a minister in two pages, it is not finished.
Uncomfortable advice
We are appointed to say the difficult thing early, while it is still cheap.

Conflict register

Peer review
Positions are reviewed internally before they reach a client board.
Built on senior engineering experience.
CMx was established by senior engineering and infrastructure specialists who had spent their careers on mission-critical programmes, and who saw the same decisions being taken without the evidence to support them. The practice is organised to advise across the whole decision, from strategy and investment through delivery, commissioning and operational assurance.
